To all whom it may concern: Y

Be it known that I, ARTHURW. PALM, a subject of the King of Sweden,residing' at Minneapolis, in the county ofHennepin and State ofMinnesota, have invented certain new and useful Improvements in Storm-Sash Holders, of which the following isa specification z ware and themain object is to provide an improved, ellicient and practical stormsash opener, closer and holder. Further objects will be disclosed inthecourse of the following specification and are illustrated in theaccompanying drawing, in which:

Fig. 1 is a sectional elevation through a common and well knownconstruction Vot window frame and sashes, embodying' myinvention.

Fig. 2 is an enlarged sectionaldetail corresponding to the lower portionof Fig. l,

,y but showing the inner sashV and the storm Y sash as closed.

Fig. 3 is a horizontal Yvie-w through the window sashes and rame,asseensubstan-.

tially when looking down in Fig. 2.

Referring to the drawing by reference characters 3 designates a windowframe, having an inclined Vwindow sill Vt, parting strips 5 and stops 6and 7 between which slide the inner and outer window sashes 8 and 9, allof common and well known construction. In a recess 10 of the frame 3*-ispositioned the storm sash 11, the same beingl hung by suitable hinges,as at 12, in the customary manner. v

The invention is embodied in a device which is co-operatively connectedto the inner sliding sash 8 and the stormV sashr11, and consists, inthemain, of a. pair of comparatively stiff coil springs 13, which Yarepivotally secured at their lower ends, as at 14, to the lower bar of theinner sash 8, and are similarly secured at their upper ends to thevertical rails of the storm sash, as at",V 15. Said lower bar of theinner sash 8, is further provided, at aboutfits middle, withV a rigidhook member 16, adapted to engage in a small bracket 17, rigidly securedon the lower rail' of the storm sash 11. SomeY sort of a latch, suchas18 (see Fig, 1),' is

used to lock the. sliding sashes 8 and 9 together when they are closed.Y Y f When the invention has been properly constructed and applied to awindowconstruction,v substantially as shown in the i readily understoodthat when the inner sash 8 is raised Vit will'cause the storm sash 11.to open to any extent desired. It will also be understood that thesprings 13 are stiff` enough so that they will not buckle upv or f bendout of shape when in a position, as Jjor This invention relates tobuilders hard-f also be "drawn in and closed. leverage or pull on thestormsashdecreasesV as the springs 13 assumemore vertical posi- Vvariousviews of the drawing, it willbe vcof it will further be obvious that thestorm sash will Y Butas the tions, I vhave arranged 'the connections 1at the ends of the springs so"v that the springs will be stretched outoftheir normal posi-- tions by the time theinner sash is iullyY 'yclosed, This provision will provide av greater pull ou 'thestorm sash,whenmost n'e`eded,"-v and` will alsol permity the sash to v'be raised#sufficiently to enable an instrument to' bev usedY againstA the stormsashy to force it open when it is stuck orfrozen in its recess. Y Thecoilspring construction thus far described is usually adequate andsuicient for the purposes mentioned, but it is occasion ally found thatthe stormrsash will rattle n Y from a strongV wind, when closed, and toovercome this objection I have provided the hook 16 which automaticallyengages in the i Y bracket 17 and positively holds the window llsecurefrom any vibrations whatever.

It is understood that the details of this invention, as herein setforth, are subject to many modifications, providedthe same come withinVthe spirit .and scope ofthe appended claims. What Iclaim is: l i

1. In combination with a vertically slidable Vwindow sashand a stormsash adapted to be swung Voutwardly therefrom, coil springsV connected'attheir upper ends to the 1 slidable window sash.

.storm sash and at their lower ends tothej Y i slidable window sash anda storm sash adapted to be swung outwardly therefrom,a

.pair of normally rigid coil springs, ref spective means for pivotallysecuring the lower 'ends of the springs to the sliding sash and theirupper ends to the storm sash.

In testimony whereofA IaLX my signature. Y
